O’Neill & Brown is a group of family-owned companies established in the Canberra and Queanbeyan region over 50 years ago. From modest beginnings in the plumbing industry, O’Neill & Brown has grown to include the fire and electrical trades, steadily evolving into one of Canberra’s largest service and construction contracting firms. O’Neill and Brown has always remained focused on developing employees and on our clients’ needs. With this at our core, we have taken on and successfully delivered some of the largest and complex projects in Canberra’s history.
